The geographer Oriol Nel·lo (Barcelona, 1957) has just made, together with the Madrid architect Agustín Hernández and with essential infographics by the also geographer Joan López, one of the most relevant contributions in recent years to the eternal debate between Madrid and Barcelona. The book Barcelona/Madrid, per un diàleg crític –which for now can only be found in Italian, but which will soon be published in Catalan by the publisher Tirant lo Blanch– was presented a few days ago at a conference of the Metropolitan Strategic Plan (PEMB) and is a commission from the Federico II University of Naples.
